I am happy about bundle package, but I am lesser happy about Canonical/Ubuntu stuff, anyway flatpack is older and more reliable than snap, is a community project and not a secret project by a crew of fanboys, most important is not hosted in a proprietary server and you don't need to subscribe any CLA. If I have to choice which bundle of course flatpak is my choice.However when snap is under a huge marketing campaign for not what reason, I feel these bundle software are a good opportunity for me to try some software which is really impossible to compile, I think is more reliable using a bundle instead to do: make, make install, make uninstall. Now I could try easily Gimp, Krita or Scribus development branch without going crazy because I am not able to compile them.

I have serious doubts as to the ability of the flatpack and/or snap packagers to properly maintain all the depends in each package. IMO the current method has served very well and spreads out the responsibility of maintaining/patching packages. Do we really expect a packager of xyz snap or flatpack to also be an expert on all of the dependencies in question? This sounds like openSSL all over again, except across many distros.
